Real-time detection of fertile window

Ava is clinically proven to detect the very beginning of the fertile window—in real time, as it happens. That’s totally different than LH tests, which only detect the last day or two of the fertile window, and the temperature method, which only confirms ovulation after the fact.

Ava is still there for you once you conceive. Once you get pregnant, get a whole new app experience with detailed explanations about what to expect in each week of pregnancy. You’ll be able to continue tracking your sleep, physiological stress, and resting pulse rate, as well as compare your weekly weight gain to standard recommendations.

Received my bracelet in August and started using it immediately…first and second cycles it predicted my ovulation to be about a week later than I had been thinking…and guess what? I am now pregnant. On my SECOND CYCLE with the Ava bracelet. I’m officially a fan.Lizzie

I had migraine headaches randomly throughout the month. With Ava, I realized that I always get them like clockwork right after I ovulate. Ava didn’t solve my headaches (if only!) but it does help me be more prepared for them, so they never take me by surprise anymore.Nurit
